CAUTION:
lug to the grounding and power cables that you supply. A cable with an incorrectly
attached lug can damage the router.

Grounding Cable Specifications

The grounding lug required is a Panduit LCD10-14B-L or equivalent (not provided). The grounding lug
accommodates 14–10 AWG (2–5.3 mm²) stranded wire. The grounding cable that you provide for the
chassis must be the same size or heavier than the input wire of each power supply. Minimum
recommendations are 14–10 AWG (2–5.3 mm²) stranded wire, 60° C wire, or as permitted by local code.

MX10003 Router Clearance Requirements for Airflow and Hardware
Maintenance
When planning the installation site, allow sufficient clearance around the rack (see
For the cooling system to function properly, the airflow around the chassis must be unrestricted. Allow
at least 6 in. (15.2 cm) of clearance between side-cooled routers. Allow 2.8 in. (7 cm) between the side
of the chassis and any non-heat-producing surface such as a wall.
For service personnel to remove and install hardware components, there must be adequate space at the
front and back of the router. At least 24 in. (61 cm) are required both in front of and behind the router.
NEBS GR-63 recommends that you allow at least 30 in. (76.2 cm) in front of the rack and 24 in. (61 cm)
behind the router.
To accommodate power cable bend radius at the rear of the chassis and the interface cable bend radius
at the front of the chassis, provide at least 2.75 in. (7 cm) at the rear and 3.5 in. (8.9 cm) at the front.
Before router installation begins, a licensed electrician must attach a cable
